英文摘要carbon-supported binary ptsn catalysts with varied alloying degree were synthesized in different processes and denoted as ptsn/c-b, ptsn/c-eg and ptsno(2)/c, respectively. x-ray diffraction (xrd) characterizations showed that ptsn/c-b catalyst displayed the highest alloying degree, while ptsno(2)/c catalyst had the lowest one among these samples. x-ray photoelectron spectroscopy (xps) results revealed that the non-alloyed sn existed in an oxidized state on the surfaces of these catalysts. by evaluating the electrocatalytic activity and analyzing the final products of ethanol oxidation reaction (eor) on these catalysts, it was found that ptsno(2)/c catalyst enhanced the products yield of acetic acid products and ptsn/c-b catalyst promoted the entire activity for eor. it was proposed that non-alloyed sno(2) species enhanced the bi-functional mechanism, whereas ptsn alloy phase strengthened the electronic effect of ptsn/c catalyst.
